You can extract tarball and copy the "libflashplayer.so" file into ~/.mozilla/plugins, as the page you posted instructs, until the devs come from hiking trip _________________Anyway it's all the same at the end...
Need help to get it working: "x-fi surround 5.1"

(working on amd64 USE="32bit 64bit multilib". 32bits plugin untested).
changelog from adobe-flash-10.2.159.1_p201011173.ebuild:
- license is now AdobeFlash-11 according to http://labs.adobe.com/downloads/flashplayer11.html (needs mirroring)
- version string handling reworked a bit, far from optimal, but it works for that specific version
- inherit rpm not needed anymore and new src_unpack because upstream has now 2 proper .tar.gz for 32bits and 64bits- removed the memcpy-to-memmove hack, not needed anymore, according to https://bugzilla.redhat.com/show_bug.cgi?id=638477#c287
- none of the tarball has readme file).

The ebuild in portage doesn't work for me in Konqueror KHTML mode. No flash, instead a popup saying "We are sorry, nspluginviewer closed unexpectedly".

Seems to work in WebKit mode though..._________________If ~amd64 ebuilds are cutting edge, then git-9999 ebuilds are chainsaws.

The only thing that adobe-flash (11) ebuild achieves is stopping your flash from working. I had manually installed Flash 11 and replaced it with ebuild one and that's what happened. How hard is it to make ebuild that copies single .so file to /usr/lib/firefox/plugins?

Obviously you messed something with your "manual" method, new flash works for me on amd64 and x86. Also, you should take a look at the ebuild to see what it actually does, a lot more then copying .so file. And adobe flash is not "firefox only" plugin, you should take a look if maybe that is your problem...

As hard as writing 172 lines in one ebuild (228 with comments and blank lines). Be sure everyone involved in Gentoo appreciate your support.

cant believe im gonna say that but flash is working great on 64bit(so far, no nvidia artifacts, not freezing X...).

First, great job devs get the official ebuild out...second, I've never had any of the problems you've described...but this version crashes just as often for me as the previous version, which is fairly regularly. Fortunately, with chromium, I just have to refresh the page to get it back again.

I had 99% crash rate on youtube videos, but a few TV sites worked and a few custom flash things were intermittently crashing and/or hanging the system. This is with firefox-bin.

The update adobe-flash-11.0.1.60_beta201107131 solved all crashing problems for me.
Now I can even view multiple youtube videos at the same time as I open custom flash and TV feed, with no hanging or crash.

I had been using 10.2.159.1_p201011173 with no problems. I wasn't able to upgrade to 10.3.* because those versions required 32-bit multilib and I run a 64-bit-only system. Now I've upgraded to 11.0.1.60_beta201107131-r1, and Konqueror is crashing more often than I'm closing browser windows of my own volition. Flash does seem to work sometimes, but often crashes Konqueror entirely. I'm using KWebkitPart, FWIW.
